I think the Easton Stealth with the stiff handle is an excellent bat as well as the Louisville Dynasty or Omaha. Most college teams I see seem to use the Omaha (those sponsored by Louisville and although they can choose other models, the Omaha seems to be the overhwhelming choice).
In mid-Feb to March, Louisville is coming out with a bat called the ExoGrid. It has carbon fiber throughout the handle I believe for added stiffness/strength. It is supposed to be the future of design (or marketing ). I think it may actually swing itself .
go to the websites of any suppliers like Baseball Warehouse, etc. most have a blurb about this bat which is being hyped as the greatest bat in the history of bats. I know it costs more than my first car.
